The Audi cars, known for luxury on par excellence, will soon be fitted with 8-speed tiptronic transmission in Q7 models. The major advantage of this transmission is the provision of engine running close to its ideal operating point allied with optimum efficiency. Also, the fuel consumption will be less (5%less than normal) and the technique is relied on 6-speed unit having an additional friction –clutch shift element. There is also torque converter lock up clutch to eliminate slip at low speeds, by which fuel can still be saved. The mechanism of 8-speed tiptronic transmission makes the transfer of engine power to the Quattro all-wheel drive train. Out of the power, 40% goes to the front while the remaining 60% goes to the rear wheels. However, due to the road conditions, the mechanism may vary making the level in the range of 65%-85% to the rear itself. The Audi Q7 fitted with this 8-speed transmission is likely to come off in this year end.(Limited edition of Audi Q7 4.2 TDI)
